Specification-forrning part of Letters Patent No. 175.114, dated March21, 1876; application filed V January 22, 1876.

To 'all whom it' may com-em: 4

Be it known' thatwe, EDWIN N. LAPHAM and J OSEPH LAPHAM, of Peru, in theconnty of v Ulinton and Stateof New York, have invented new and ImprovedMiddlings-Purifier, of which the followi g is aspecification:

The invention consists of a hollow trunk or chest standignearly upright,havin g clusters 'ut' stationa'y beate'rs standing acrossit, and valvesin the lower side at certain distances `part, and turning into ahorizontal direction ,in the upper part, ins which are' other beaters,

with a hopper below for returns, into the lower 'part of which trunk theniddlings are' fed above a fan, whicljblows the middlings up past theb'eaters, Whith disitegratethe lumps and break oli' the heavie'r fromthe lighter pari ticles, so that the latter are earried ofi: through thebra -sp01 t,'3 while the, forne'' 'escape through the valvesandare'condncted away', and the returns are conducted from the hopper backinto the nachineagain'for beingworked over. i

Figurelis a sectional'eleration of our improved pnrifier, and Fig. 2 isa front elevati'on. Similar letters of reference indicate oorre spondingparts. y i v.

A represents the i hollow trunk, 'which stands early up'ight, and hasthin,flat, or other shaped stationary beaters, B, extendin g across fronthelower side to: the 'upper one,

' and preferably located in groups or clusters at certain intervalsof'space along the? upright portion of the trunk, and the back-or lowerside has a number of ipassages, C, for the escape of the niddl-ings intoa spout, D, for conducting them away, the passages being regulated byvalves M. The trnnk bends over at E into a horizontal portion, in whichare other 'stationary beaters, B', and below them `is a hopper, F, forreturns. The middlingsare fed into the truk at G from a hopper, H, by aroller, I, and regulated in quantity by'a slide, K. From the inlet Grthey are blown p along the trunk against the beaters by the fan J thelight particles being separated and carried ofi' to the hran-bin throughE, whilethe heavier portions fall through the valvcs, and the returns goback into hopper H rby the spout L, to be worked over again. The lowervalve M islonger than the others. and is adjusted so as to concentratethe blast on the feed-roller, thereby subjecting the middling's to astrng blast at the time of entering, and before they canfall into thepassages C. v

Having thus described our nvention, we

claim as new and desire to secure by Letters Patent 1. The combinationof hollow inclined trunk A, stationary beaters 'B, passages C, valves M,and fan J, substantially ass'pecified.

2. The horizontal portion E` of the trunk, stationary beaters B',hoppers F, and spout L, combined with the inelined `trunk A and fan J,substatially as specified;
